Which countries are included in the international norm?
For BRIGHT, the International norm is based on the national norms (in all N = 15,138):
- Norway (N=2,409)
- Denmark (N=1,007)
- Sweden (N=8,691)
- Finland (N=2,320)
- Mexico (N=711)
The International norm is a weighted average of all the local samples, ensuring equal representativeness for all countries included. National samples are included in the International norm if they have at least 300 responses locally.
